Choice A is faulty because the pronoun it and the appositive a practice each lack a noun referent. Nor are there logical referents in choice B for as is and it. Choice C entails a false appositive: the sentence now says that the single strain of plant is itself a practice fostered by modern seed-marketing methods, not that the use of a single strain is such a practice. Choice D reverses the order of the constructions, but the appositive remains illogical. Choice E is correct: use is the proper subject for the verb increases and a logical governing noun for the appositive practice. This question is of middle difficulty.

这个是OG的解释，比任何人的解释都好

另外，楼主有没有下载 “大全注释”呢，好好利用CD的资源，一定对你有很多帮助的

OG解释中的 the appositive a practice each lack a noun referent，为什么practice这个名词需要一个指代对象呀？practice做谁的同位语？哪个牛人能分析一下句子结构？

还有，OG解释是哪里找来的？

“楼主没有下载 “大全注释”呢”请问怎么下载？XDF250题和大全对应关系是怎样的？

A practice 其实是前面整句话The use of a single strain of plant for a given crop over a wide area的一个说明，做其同位于，并被 fostered by modern seed-marketing methods修饰说明

AB都是不知所云, it指代的十分不明确, 相比之下E多爽快.
